<noscript><B>Please enable JavaScript to see the demo.</B></noscript> This demo shows that you can move an ad under the victim's mouse so that the only thing they can do is click on the banner ad that is placed under their mouse.  Try to click <a href="alert('mouse jacked!')">here</a> as an example.  It should show a popup.  But instead you will be subversively clicking on an iframe which would contain your banner.
<script type="text/javascript">
if (document.getElementById || document.all)
